MetaBones Speed Booster Adaptor

It is weighting as much as a native MFT lens (194gr) and cost as much if not more (600$) : I don’t see much interest in that adapter for stills shooters, once you add the weight of an EOS lens. Plus it is made primarily for APSC mirrorless : they would get the original focal back, but not 4:3 users. So it is even less interesting for MFT photographers.

As for the rest, you are just relaying what the marketing says : reducing the image circle will of course make the original flaws appear smaller in the picture. What they don't tell you is how many flaws the piece of glass they stick in their adaptor will add.

Anyone wants to mount a heavy EOS lens on his small mirrorless camera and add 200grmore to it ? And s willing to pay as much as a native mft lens for it ?
